Detailed explanation-1: -A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.
Detailed explanation-2: -The major disadvantages of asexual reproduction are: Lack of diversity-Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.
Detailed explanation-3: -It takes time and energy to find a mate and reproduce. Reproduction through sexual means is uncertain. Favorable genetics might not be passed to the offspring. Fewer offspring are typically produced. It can be deadly. 15-Nov-2017
